A faulty seal is being blamed for Volkswagen's decision to stop sale of 25,000 Passats, Beetles and Jettas that came with a particular turbocharged engine.

The seal, called an o-ring, connects to the automatic transmission cooler. It can spring a leak, leading to the possibility the oil could catch on fire in vehicles that came with 1.8-liter turbocharged engines. But Volkswagen says in a statement that no accidents, fires or injuries have resulted from the glitch so far.

All the cars involved in the issue were made since Feb. 1.

So far, VW is not advising owners of the near-new vehicles to stop driving them. The order, for the moment, only applies to dealers, who are being told to stop selling them until they can be fixed. VW says it is contact with federal safety regulators and a recall order is likely.

"There have been some complaints from customers -- oil leaking on the ground," says spokesman Mark Gillies.

Passat is made at Volkswagen's factory in Chattanooga, Tenn. Jetta and Beetle are manufactured in Mexico. The 1.8-turbocharged engines come as standard equipment in Passat and Beetle.
